SAFETY BOX STRUCTURE Patented July 117, 19151 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a safety box structure and while the invention might have various applications it particularly is designed for use in homes, offices or small stores, etc. It is often desirable to have a strong box or safety box in a residence in which jewelry and other valuables can be kept, which box can be disposed or placed in an inconspcuous location. Such a box is also desirable in an oiice, small store or the like, where the amount of cash or valuables on hand does not warrant the possession of a regular large safe.

It is an object of this invention to provide a simple, strong and eiiicient structure of safety box which can be placed in a hidden or'inconspicuous location, and one which is preferably fireproof.

It is a further object of the invention to provide a safety box comprising simple and effective means by which it can be secured to a floor.

It is another object ofthe invention to provide a safety box comprising a locking means secured to a floor, means on said box cooperating with said locking means and movable into cooperating relation therewith by a longitudinal movement of said box, a pin preferably being provided extending through said box and into the floor for preventing longitudinal movement of said box to disengage said locking means.

It is a further object of the invention to provideA a safety box structure comprising a casing preferably of rectangular form in cross section, said casing having al chamber therein open at one end and a door of novel construction fitting in and closing said end.

These and other objects and advantages on the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which- Fig. l is a vertical section taken substantially on line I-I of Fig. 4;

Fig. 8 is a partial vertical section taken online 2 8 8 of Fig. '7, all of said sections being taken as indicated by the arrows; and

Fig. 9 is a view in front elevation of the device with the door removed.

Referring to the drawings, a device is shown comprising a plate I0 of comparatively' small thickness which will engage the top of a floor I I, such as a concrete oor. Members I2 are secured to plate I0 and floor II, and while these might vary in form, in the embodiment of the inventicnillustrated they are shown as spaced plate-like bars extending transversely across plate I D, which plate, as shown in Fig. 6, is of somewhat elongated rectangular form. The bars i2 are spaced above plate il) by spacing washers I3 and securing headed bolts Id extend through bars I2 and members I3 and I into the floor II, as shown in Figs. l and 8. A casing Iii is provided and while this casing might take various forms, in the embodiment of the invention illustrated it is shown as rectangular in transverse section and of somewhat elongated form. Casing I6 has an outer wall Ita which will be made of plate-like material, preferably steel, and an inner wall |617 spaced some distance from the outer wall l 6a. The space between walls i @a and i612 will contain some lling material such as a good insulating material Il. Wall Ib will preferably be made of sheet metal which may be of lighter gauge tha-n the metal of wall Ia. Wall Itb has a chamber therein open at one end and wall Ib flares outwardly at said open end and has an outer portion Ic extending at right angles to and engaging the side portions of wall ita. Walls Ita and ISb will preferably be welded into integral pieces and portions iBc will preferably be welded at their outer edges to wall ita. The vertical side portions of wall ita are extended downwardly somewhat and have plate-like portions ISd extending inwardly th trefrom at their bottoms. (See Figs. 1, 3, 7 and 8.) Other similar but shorter portions Ie also extend inwardly and are spaced some distance from the adjacent ends of members Id. Members ld and Ic are in the same plane. The length of the space If between members Ite and Iid is slightly greater than the `width of bars I2. As illustrated in Fig. 3, it is apparent that casing IG can be placed with members ltd and Iie resting on plate I0, the bars I2 nearest the front end of the casing having passed through the opening or space I6f. It will also be seen that casing I6 can then be moved rearwardly and portions Ie will move under the forward bars l2 and portions IGd will move under the rear bars I2, as shown in Fig. 1.

The sides of wall Ia extend forwardly some distance beyond portions ISC and a plurality of plates I8 are disposed about and in engagement with wall Ia. The inner edge portions of plates I8 are arranged in stepped relation and at the top and sides of wall ISa the innermost plate I8 projects farthest toward the center of said casing. At the bottom side however the outermost plate i8 projects farthest toward the center of the casing. Said outermost plate I8 at the bottom also has its top beveled outwardly, as shown at 58a in Figs. 1 and 2. A door 2i) is provided, the same having an outer plate 20a which at its top and sides fits within the top and side portions of wall Ita and at its bottom fits against a plate ESQ which extends between the sides of wall iSa and has its front surface flush with the front edges of wall Ia. Plate I6g extends downwardly to the bottom of plates or portions |66. Door 2D has an inner wall 20h having a tapering portion arranged to nt in the flaring portion of wall Ib. At the top and sides of door 20, wall 28o has a portion 2llc extending substantially perpendicular to and engaging the inner side of plate 28o to which it preferably Will be welded. The space between plate 20a and wall 20h will also be filled with suitable packing material such as a good insulating material 2 I. Said door also comprises a plurality of plates 28d which extend about portion 20c in engagement with the outer side thereof and extend across said door at the bottom thereof. Wall 28h at the bottom is bent vertically to engage the inner plate 28d, as shown in Figs. 1 and 2, the top edge of said vertically bent portion being flush with the top edges of plates 20d. The plates 20d engage portion 20c at their inner edges, which edges are in one plane, but the outer edge portions of plates 28d are arranged in stepped relation. At the top and sides the outermost plate 26d extends farthest toward wall I6a. At the bottom of the door however the innermost plate 28d extends farthest toward wall Ia. It will be seen, as shown in Figs. 1 and 2, that the stepped plates 26d fit the stepped plates I8 when the door is in closed position, the inner edges of the plates I 8 engaging the outer edges of plates 28d. In the embodiment of the invention illustrated there are three each of the plates I8 and Zd and the two innermost plates 20d at the bottom of the door have their bottom edges rounded, as shown at 28e.

The outwardly flared portion of wall IEb at its bottom is provided with a recess IGh centrally thereof, as shown in Figs. 2 and 5. A headed pin 2li extends through the bottom of wall IBb through the bottom of wall Ia and through plate It into floor Il. The head of pin 24 is disposed in recess 16h, and is shown as slotted. A lock 25 is provided for door 28 and is secured to plates 2G11 and to a lug 28T welded to the inner side of plate 20a, by headed screws 21. Lock 25 has a key-receiving portion 25a extending through an opening in plate 28a and having its front surface flush with the front surface of plate 28a. Lock 25 will include one or more tumblers or bolts 25D which can be moved by the key of said lock into position in the rear of the innermost plate I8, as shown in Fig. 2. The chamber itk in wall Ib will be adapted to hold some receptacle which could be in the form of a box 28 open at its top and having a handle 28a at its front side.

rlhe members Iii and I2 can be placed beneath the floor f a room and be covered with casing I6 by a trap-door or panel, or said members could be placed in the rear of a baseboard in a room or even in a pocket in the wall of a room. The valuables to be stored will be placed in the receptacle 28 and the same disposed in the chamber in wall Ib. Door 20 will then be placed in position by placing the bottom side in the position shown in Figs. 1 and 2 so that plates 20d have their lower portions at the inner sides of plates I8. The door will now be tipped or swung inwardly and come into the position shown in Figs. 1 and 2. The key in lock 25 can now be turned and the tumbler or bolt of said lock will move into position in the rear of innermost plate I8 at the top of the said casing. Before the door 28 is so placed in closed position, however, the casing I6 will be placed on plate lll, as shown in Fig. 3, the spaces If accommodating the forward bars I2. The casing will now be pushed rearwardly to the position shown in Fig. l, and plates 56e will pass under forward bars I2 and plates 16d will pass under the rear bars I2. The casing is now locked against vertical movement. Pin 24 will now be dropped into place as it will be in alinement with the hole in the plate Iii and floor Il. Door 20 will now be closed and locked, as above described. It will ybe noted that the plates 20d at the `bottom will prevent forward movement of the door if lock 25 has been forced or blown out by an explosive. The door does not have side hinges and this might prevent its being opened by any unauthorized person trying to enter the box. When the door is unlocked and swung forwardly, the pin 24 must first be removed before the casing can be moved forwardly to be lifted. Anyone attempting to enter the box illegally might not remove pin 24 and would not know that casing I E has to be moved forwardly to be lifted. A very strong and secure safety box is thus provided.

From the above description it Will be seen that I have provided a simple and very efficient structure of safety box or strong box. The same is adapted to be disposed in a hidden or obscure place. The casing used is locked in position by simple and ecient means and is effectively closed by the door thereof. The chamber Ilc is f'lreproof and well protected by the reproof insulation material 2l. Articles in receptacle 28 would thus be secure against re. The device can be easily made from simple and easily procured material, the same has been amply demonstrated in actual practice and found to be very successful and ecient.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims.

What is claimed is:

1. A safety box structure having in combination, a casing having a chamber therein, laterally spaced inwardly extending members on said casing at vthe bottom thereof, said members having alined openings in their adjacent sides, members secured to a floor and spaced above the same, said second mentioned members being of a width to pass through said openings whereby said casing can be moved downwardly so that said second mentioned members can pass through said openings and then move longitudinally to bring portions of said first men-- tioned members beneath said second mentioned members.
